SIMO type low-input and high-output impedance current-mode universal filter employing three universal current conveyors

In this paper, the Universal current conveyor (UCC) is presented. The paper also contains UCC application possibilities and an outline of its internal structure. Real parameters obtained by measurement are also included. This circuit can operate as almost any known type of current conveyor of all three generations and even as some other types of active element. In the paper, the single-input multiple-output (SIMO) universal filter solution employing three UCC elements is also shown. This solution has many beneficial features and offers all kinds of transfer function in both inverted and non-inverted form and that is why this topology is suitable to be included in the library of functional blocks. The paper also contains experimental results, whose goal was to verify real parameters of the designed block. (C) 2009 Elsevier GmbH. All rights reserved.
